I have some questions about rack systems... I noticed that breeders only have one hide in the tubs. So from what I understand the hide is over the heat tape (or similar heating source.) So how does the snake thermoregulate. Is it because they are in a tub so it is all dark? I don't know, it's just a thought. And how do they regulate and moniter humidity? Do they just stick a humidifier in the room and keep the whole room up to par? Thanks, and by "they" I just mean anyone who has racks.
